ABSTRACT
Earlier research on infant measures focused on the relationship of total developmental scores with later developmental scores. The more recent research has studied the relationship of developing specific abilities to later measures. The results of these studies have provided a confirmation for the concept that there is a continuity in the development of both intellectual and language functions which can be measured early and which is predictive of later outcome. The controversy continues not only about the contribution of genes versus environment to later intelligence, but as to how early one can predict cognitive outcome. There has been a recent emphasis on prediction for high risk and premature infants. The results of the Kohen-Raz subscales correlations with language measures and developmental test measures are highly comparable to those of Siegel. Different patterns of behavior are predominant at different ages, and are related precursors of later more complex behavior and development.
